Really? It was 25 mph on other Regions in the 1960 Appendix but of course the WR ones don't show speeds. In the WTTs perhaps?

Sounds scary . . .

GWR Notice No 166 on introduction of Auto Token Exchange apparatus on the Minehead Branch 6 July 1934 states inter alia "The speed of trains must not exceed 40MPH when exchanging". Similar clause in Notice No 118 for Auto Token Exchange Apparatus Instructions for the Minehead and Barnstaple Branches. Referenced from article by Mike Christensen in British Railway Journal 34.

IIRC 40MPH was also the limit on the S&DJR.

....... and I can certainly confirm that they did exchange at around 40mph on the S&DJR, even in its very late days. The first "bang" that I heard was so loud that I initially thought that a detonator had gone off.

Interesting. The S&D was, of course, latterly Western Region.

Well, most but not all of it, but we prefer not to dwell on that misfortune :cry:
